The other day I was walking around the trailer with some thick cotton winter socks. They are very comfortable right up until you step in some water that was spilled on the floor. There is water on the floor in the winter from snow on footwear and people showering and dishes being done and such.

Slippers do the job of keeping your feet dry from little wet spots on the floor but they often fall off the feet and are just a bit of an annoyance to deal with. The solution then is to merge slippers with socks. People have different size feet so this sock slipper would come in various sizes. It could also have insoles ability if you wanted it to. A pocket could be created between the velcro surface and the waterproof rubber slipper sole.
